Abstract
ABSTRACT Design of laterally loaded piles relies on a number of theoretical and numerical approaches. Finite Element Analysis (FEA) offers a good alternative to study pile’s response under lateral loading due to adjacent variable vertical surcharge and excavation depths. The piles groups’ behavior under lateral loadings is modeled by three dimensional finite element analyses. The results are presented in this thesis. The effect of pile diameter, spacing, driven depth and excavation depth were investigated. In addition, an effect of soil type, variable surcharge values and excavation depths were also studied in this analysis. Linear elastic model was used for modeling the piles. Mohr-Coulomb model was used to simulate the surrounding soil. A parametric study was carried out by varying the key parameters to demonstrate its effect on pile behavior. The values of maximum pile responses are then normalized to develop design charts that can be used for estimating the approximate values of maximum pile deformation.
